Worth noting

• The Braves opted not to pitch Jordan Walden in Tuesday's game against the Nationals because of a sore back. Walden will likely throw a bullpen session within the next couple of days and then be used in a game by the end of this week.

• The Braves signed each of their 20 players who have not acquired enough service time to be eligible for arbitration.

• Yohan Flande surrendered a home run to Don Kelly on Wednesday and has now allowed seven earned runs in three innings this year. Last year, Flande allowed one run in 12 1/3 innings and might have gained an Opening Day roster spot if the Braves had not signed Livan Hernandez in late March.
